Example of the optimal Kelly betting fraction, versus expected return of other fractional bets. In probability theory, the Kelly criterion (or Kelly strategy or Kelly bet) is a formula for sizing a sequence of bets by maximizing the long-term expected value of the logarithm of wealth, which is equivalent to maximizing the long-term expected geometric growth rate.
For example, on the 11th of April 1988, 41 players selected 244 as the winning combination. Three days later only 24 individuals selected 244, a 41.5% decrease. This is the gambler's fallacy in motion, as lottery players believe that the occurrence of a winning combination in previous days will decrease its likelihood of occurring today.

A simple example formula that would achieve this (expanding on the aforementioned example) would be simply to calculate the jackpot as being $1,000 plus the square root of a random number between zero and four million, which would result in a 75% probability of each jackpot being between $2,000 and $3,000 and a 25% probability of a jackpot ...
